[Nix-dev] Gratuitous generations

[Christian Theune]

Hi,

last year I experimented with self-managing NixOS installations. One thing that I stumbled upon was that regularly triggering nixos-rebuild would create new generations even though the config hadn’t changed.

Is there a way to suppress that or a reason why this can’t be suppressed in general?

What I want is to create a simple cronjob that generates Nix OS configuration from an upstream “source of truth”, like users, and not think about convergence but just trigger nixos-rebuild after updating the config. If nothing changed then no new generation should appear IMHO.

Thoughts?

Christian
